rule

basic rules

• Use #as comment
• In .gitignorea file, each line represents a pattern;
• Empty lines do not match any files;
• git tracks files, not directories;
• .gitignoreEven setting ignore in has no effect if the local repository file is already tracked .
• .gitignoreThe files will also be uploaded to the remote warehouse, so people in the same warehouse can use the same .gitignorefile.

---

ignore files and directories

folderName

• Indicates that the folderName file and folderName directory are ignored, and src/folderthe files and src/utils/folderfiles will be ignored, that is, they will not be submitted to the remote warehouse.
• Will automatically search multi-level directories, such as: */*/folderName.

---

Ignore folderName files only, not folderName directories (!)

The schema looks like this:

folderName
!folderName/

• Reverse operation !: Indicates that the previously ignored matching pattern is included in the trace content again.
• src/folderName files, src/utils/folderName files will be ignored, and folderName directories with the same name will not be ignored.

---

just ignore the directory /

folderName/

Ignore folderName directories, including:

• The foldernName under the current directory, for example: folderName/;
• folderName under the multi-level directory, for example: */*/folderName/;
• src/folder files and src/utils/folder files with the same name are not ignored.

---

Use wildcards * ? []

Commonly used wildcards are:

• Asterisk *: match multiple characters;
• Question mark ?: match any character /except ;
• Square brackets [xxxx]: match characters in multiple lists;

$ tree
.
├── src
│   ├── add.c
│   ├── add.i
│   └── add.o
├── test.c
├── test.i
└── test.o

1 directory, 6 files

---

Among them, the contents of the .gitignore file are as follows:

*.[io] 

• So in the local warehouse, test.ifile, test.ofile, src/add.ofile, src/add.ifile will be ignored
• test.cFiles and files are not add.cignored.
• The matching patterns ignored here are multi-level directories.

---

Multi-level directory**

A slash followed by two consecutive asterisks **indicates a multi-level directory.

src/**/file 

It can mean ignore src/folder1/file, src/folder1/folder2/***/foldern/fileetc.
